Abstract: This paper describes the development of new forms of public–private collaboration by members of a project-based organisation as a Community of Practice (CoP) in the Dutch construction sector. Cost overruns, time delays and corruption have put pressure on the relationship between the government and the construction sector. Political and public actors are forcing the construction industry to develop new cultural practices of collaboration in public–private partnerships. The paper incorporates power relations and shows how public and private partners, together with the researchers, develop an innovative tendering process. Based upon the literature on project-based organisations functioning as CoPs, we show how temporal organisational settings can enable new forms of learning. The specific development of a CoP in the Dutch construction sector has resulted in a 3-D virtual simulation programme which can be used to experience new behaviour and to train people in new approaches.
